I had a #5000 Rolls in which I towed my 23' for years. It was at the limit but did the job. After I bracketed the boat it no longer had the length necessary to center the boats weight properly over the tandums . I now have a #7000. 24'-26' boat capacity, maybe a little overkill but the price was right
